英文摘要	Systems and methods in accordance with embodiments of the invention implement electrically tunable metasurfaces. In one embodiment, an electrically tunable metasurface reflectarray includes: a mirrored surface; a conductive layer; a dielectric layer; where the conductive layer and the dielectric layer are in direct contact, and thereby define a conductor-dielectric interface; a plurality of subwavelength antenna elements; and an electrical power source configured to establish a potential difference between at least one subwavelength antenna element and the mirrored surface; where a potential difference between a subwavelength antenna element and the mirrored surface applies an electric field to a corresponding region of the electrically tunable metasurface reflectarray; where any applied electric fields in conjunction with the geometry and the material composition of each of the subwavelength antenna elements, the conductive layer, and the dielectric layer, enable the electrically tunable metasurface reflectarray to measurably augment the propagation characteristics of incident electromagnetic waves.
